As the maglev train doesn\u2019t have any physical contact with the rails, it has to use non-contact measuring methods. The technology based on the inductive loop-cable could fulfill the requirement by using an on-board antenna which could detect the alternating magnetic field produced by the loop-cable on rails. This paper introduces the structure of a speed and position system, and analyses the electromagnetic field produced by the loop-cable. The equivalent model of the loop-cable is given and the most suitable component of the magnetic flux density is selected. Then the paper also compares the alternating current (AC) resistance and the quality factor between two kinds of coils which the antenna is composed of. The effect of the rails to the signal receiving is also researched and then the structure of the coils is improved. Finally, considering the common-mode interference, 8-word coils are designed and analyzed.<\/jats:p>","DOI":"10.3390\/s120708526","type":"journal-article","created":{"date-parts":[[2012,6,25]],"date-time":"2012-06-25T16:55:20Z","timestamp":1340643320000},"page":"8526-8543","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Analysis and Design of a Speed and Position System for Maglev Vehicles"],"prefix":"10.3390","volume":"12","author":[{"given":"Chunhui","family":"Dai","sequence":"first","affiliation":[{"name":"College of Mechatronics Engineering and Automation, National University of Defense Technology, ChangSha 410073, HuNan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fengshan","family":"Dou","sequence":"additional","affiliation":[{"name":"College of Mechatronics Engineering and Automation, National University of Defense Technology, ChangSha 410073, HuNan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianglei","family":"Song","sequence":"additional","affiliation":[{"name":"College of Mechatronics Engineering and Automation, National University of Defense Technology, ChangSha 410073, HuNan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiqiang","family":"Long","sequence":"additional","affiliation":[{"name":"College of Mechatronics Engineering and Automation, National University of Defense Technology, ChangSha 410073, HuNan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2012,6,25]]},"reference":[{"key":"ref_1","unstructured":"Yasuda, Y., Fujino, M., Tanaka, M., and Syunzo, I.
